Dr. Manish Sadarangani, the Sauder Chair in Pediatric Infectious Diseases at the University of British Columbia: "at least 90-95% of the population need to be vaccinated" (https://www.ovg.ox.ac.uk/news/herd-immunity-how-does-it-work)

Sebastian Funk, Associate Professor at the Centre for the Mathematical Modelling of Infectious Diseases at the London School of Hygiene & Tropical Medicine: "to achieve [termination of measles transmission,] the population immune needs to be 93-95%, the herd immunity threshold."

The article that I linked shows why even 100% vaccinated population will not achieve herd immunity. This is the meat of the article really, read it.

There is a substitution of terms in the first statement that you quoted. To stop transmission you need 90-95% of the population being _immune_ to the disease, not vaccinated against it. Do you see the difference?

The second quote by Funk got it right. But again please read the article why this is unattainable even with the 100% vaccination rate.
